Answer:
In her narrative, Rowlandson continuously makes references to the bible. By doing so, she makes herself look like if she were in a religious pilgrimage.
This way of writing was kind of common in her times, specially for women who did not have a public voice.
The way she refers to Christianity can be seen when she writes about her capture, "several houses were burning, and the smoke ascending to heaven’ (2009).
She also expressed her desire to keep respect for the Sabbat day while captive, ‘when the Sabbath came they bade me go to work. I told them it was the Sabbath day, and desired them to let me rest, and told them I would do as much more tomorrow; to which they answered me they would break my face. And here I cannot but take notice of the strange providence of God in preserving the heathen’ (Rowlandson 2009).
In Puritan society The Sabbath was of great importance and by acknowledging it Rowlandson was making herself well seen by her own society. In this way she also gained sympathy from those people around her and at the same time her status in society was much better upheld.
